Olympus SZ-31MR iHS vs Panasonic Lumix DMC-ZS10: A Thorough Small Sensor Superzoom Face-Off
Choosing a compact superzoom camera often hinges on balancing versatility, maneuverability, and image quality within a restricted sensor footprint. The Olympus SZ-31MR iHS and Panasonic Lumix DMC-ZS10 (also known as TZ20/TZ22) are two contenders from the early 2010s small sensor superzoom segment, offering attractive zoom ranges and feature sets for travel and enthusiast shooters who prefer pocketable cameras over bulkier systems.
With over 15 years of experience testing cameras across every genre, I aim to dissect how these two models stack up head-to-head - not just spec sheet face-offs, but hands-on insights you won’t find elsewhere. Let’s dive deep into their design, image quality, autofocus capabilities, and practical usability across varied photography scenarios. By the end, photographers of all flavors should feel empowered to decide which camera better fulfills their creative and technical needs.
First Impressions: Design, Controls, and Pocketability
At first glance, both the Olympus SZ-31MR and Panasonic ZS10 maintain the compact superzoom tradition: offering extensive focal length range in hand-friendly packages that slip comfortably into travel bags or larger pockets.
Physically, the Olympus SZ-31MR measures 106 x 69 x 40 mm and weighs 226 grams, while the Panasonic ZS10 is slightly more compact - 105 x 58 x 33 mm - and marginally lighter at 219 grams. The Panasonic’s narrower body thickness and streamlined form factor give it a slight edge for discrete street photography or tourism where minimal intrusion matters.
Working with these cameras, the Olympus feels a tad chunkier but solid in the grip. Its slightly larger depth grants the thumb and fingers more purchase area, which some users may prefer for stability during longer shoots or when zooming. The Panasonic, thinner and sleeker, encourages a lighter handling style; it excels in quick-snapping scenarios but might feel a bit too compact during longer handheld sessions, especially in colder weather when gloves come into play.
From a controls standpoint, the Panasonic ZS10 incorporates more manual exposure options, including aperture priority, shutter priority, and full manual modes - features absent from the SZ-31MR. This makes the ZS10 a more potent tool for enthusiasts who want granular control without lugging around DSLRs or mirrorless setups. Olympus’s control layout is simplified, focusing on ease-of-use but at the cost of reducing creative flexibility - a trade-off that suits casual shooters more than serious hobbyists.
The button layout topscreen clarity and menu navigation rate about average for their era, but Panasonic’s interface suffers slightly from a lower-resolution rear screen (460k pixels vs Olympus's 920k pixels), making image playback and manual focusing a more eye-straining affair.
Panasonic’s touchscreen functionality provides some operational ease but lacks the precision and responsiveness we’ve come to expect from modern cameras. Olympus’s screen employs HyperCrystal III TFT technology, delivering brighter and crisper images that help during composition in bright daylight.
Sensor and Image Quality: Small Sensors with Big Aspirations
Both cameras rely on the ubiquitous 1/2.3-inch sensor size, a staple in compact superzooms, but their sensor architectures differ subtly.
The Olympus SZ-31MR features a 16-megapixel backside illuminated (BSI) CMOS sensor measuring 6.17 x 4.55 mm with a total area of 28.07 mm². Panasonic’s ZS10 sports a slightly smaller 14-megapixel standard CMOS sensor at 6.08 x 4.56 mm (27.72 mm²). At first blush, the Olympus holds a technical advantage in pixel tally and sensor tech, which often translates into improved light-gathering efficiency and noise performance.
In practice, Olympus’s BSI sensor delivered marginally better dynamic range and lower noise at higher ISO levels during side-by-side testing. The Olympus was consistent in preserving shadow detail under challenging lighting, while Panasonic images showed earlier clipping and less tonal latitude.
The Olympus shines in daylight landscapes and travel scenarios, where its sensor captures fine textures crisply - foliage, architectural detail, and subtle skies show richer gradation. Panasonic’s images tend to lean toward slightly punchier contrast, serving well for vibrant street snaps but sacrificing some naturalness in tricky lighting.
That said, both cameras use anti-aliasing filters to reduce moiré, affecting raw detail resolution slightly but enhancing overall image cleanliness, especially at their megapixel counts.
Lens and Zoom Versatility: Reach and Aperture Considerations
One of the main draws of superzoom compacts is versatility. Here, Olympus presents a 25-600 mm-equivalent zoom (24x), while Panasonic offers 24-384 mm-equivalent (16x). This puts Olympus well ahead in reach, almost doubling Panasonic’s telephoto capability.
This broad zoom capacity makes the SZ-31MR more attractive for wildlife or distant subjects, where getting close isn’t always possible. Conversely, the ZS10’s more modest zoom range pairs nicely with a wider aperture at the telephoto end (max f/5.9 vs Olympus f/6.9), slightly aiding low-light telephoto shooting and autofocus reliability.
Olympus’s lens isn’t as fast up front (f/3.0 vs Panasonic’s f/3.3 at widest), but the difference is marginal. Both lenses suffer the typical superzoom compromise of slower apertures at long focal lengths, limiting shallow depth of field control and low light prowess at the tele end.
Interestingly, Olympus supports macro focusing to as close as 1 cm, surpassing Panasonic's 3 cm minimum focus range. For users keen on macro shots of insects or textured details, this is a strong advantage.
Autofocus Performance: Searching for Sharpness
Autofocus (AF) technology is a major differentiator, as it directly affects the ability to seize fleeting moments sharply.
The Olympus employs contrast-detection AF with face detection and tracking capabilities, but offers only single AF mode - no continuous AF. The Panasonic also uses contrast-detection AF but adds continuous AF and boasts 23 focus points, with center-weighted metering aiding precision.
Testing in both controlled and field conditions revealed Panasonic’s AF being generally faster and more consistent, especially when tracking moving subjects such as pets, children, or street performers. Olympus's AF could occasionally hunt in low contrast or low light, and the lack of continuous AF mode hampers burst shooting for action.
Neither camera offers phase detection AF, unsurprising given their sensor class and release period, but Panasonic’s multi-point system and AF tracking compensate somewhat, producing better results in dynamic environments. Both cameras support touch AF on their screens, though the higher resolution of the Olympus panel lends itself better to precise AF point selection.
Burst Mode and Sports Shooting: Speed or Slightly Sluggish?
Continuous shooting is where compact cameras usually fall short compared to DSLRs, but it remains a consideration for sports and wildlife enthusiasts.
Panasonic takes the crown here with an impressive 10 frames per second burst rate. Olympus clocks in at 7 fps, respectable but slower.
Real-use tests showed Panasonic’s 10 fps rate sustainable for short bursts but buffer limitations and slower write speeds caused hiccups during longer sequences. Olympus ran out of puff sooner, limiting its usefulness for rapid-fire action photography.
For capturing fast sports moments - say, local soccer matches or skateboarding tricks - Panasonic’s speed advantage enhanced keeper rates noticeably. Olympus is better suited for more deliberate shooting or less dynamic subjects.
Video Capabilities: Moving Pictures in Perspective
Both cameras support Full HD 1080p video recording but differ in their approach.
Panasonic offers 1080p at 60 fps, allowing for smooth motion capture well-suited to action sequences or hybrid shooters who want video without sacrificing quality. Olympus limits 1080p recording to 30 fps, reducing the versatility for slower motion or high-action capture.
Video format support varies as well: Panasonic records in both MPEG-4 and AVCHD, the latter being a more robust compression standard favored by videographers for editing workflows, while Olympus defaults to MPEG-4/H.264.
Neither camera offers microphone or headphone jacks, which constrains manual audio control, but Panasonic’s slightly better image stabilization - a lens-based optical system - gives it a small edge in handheld smoothness. Olympus relies on sensor-shift stabilization, which performs well overall but can occasionally exhibit subtle judder during video panning.
Battery Life and Connectivity
The SZ-31MR uses Olympus’s LI-50B battery, rated for about 200 shots per charge - a relatively modest endurance that frustrated longer outings without spare power.
Panasonic’s pack lasts approximately 260 shots, an appreciable difference especially for travelers and event shooters who might not have frequent access to charging.
In terms of wireless features, Olympus incorporates Eye-Fi card compatibility for Wi-Fi transfer (though reliant on third-party hardware), whereas Panasonic offers no built-in wireless capabilities. However, Panasonic’s integrated GPS is a boon for geo-tagging travels and work documentation.
Both cameras share USB 2.0 and HDMI ports for data and playback, but neither supports modern high-speed transfer or streaming features.
Handling in Various Photography Genres: Where Does Each Excel?
After extensive side-by-side field testing covering portrait, landscape, wildlife, street, macro, night/astro, and travel photography, here are the nuanced takeaways:
Portraits: Skin Tones and Bokeh
Neither camera achieves DSLR-like subject separation due to sensor size and lens aperture, but Olympus’s longer zoom helps isolate faces better in flattering portraits. Olympus also includes face detection autofocus, enhancing focus precision for group or candid shots.
Panasonic occasionally suffers from less natural skin tone rendering, favoring vividness that may not suit all tastes.
Landscapes: Detail and Dynamic Range
Olympus’s superior dynamic range and higher resolution sensor lend it to richer landscapes with preserved highlights and shadows - a valuable asset for outdoor photographers and travel pros aiming for fine art results.
Neither camera is weather sealed, which dampens confidence in extreme environments.
Wildlife and Sports: Autofocus Muscle and Frame Rates
Panasonic’s faster burst speed and more sophisticated AF system deliver better action capture, especially at moderate zoom ranges. However, Olympus’s 600mm reach offers unique framing possibilities difficult to top in this segment.
Street Photography: Discretion and Portability
Panasonic’s slimmer profile and quieter operation helped me blend into urban environments more effortlessly. Olympus’s greater depth and zoom length call more attention but provide compositional freedom.
Macro: Close Focus and Stabilization
Olympus pulling focus down to 1 cm opens exciting close-up worlds, perfect for plant details or curiosities. Panasonic’s 3 cm minimum is less aggressive but still typical of compacts.
Overall Image Samples and Performance Scores
To illustrate, here is a gallery of samples demonstrating image quality in daylight, zoom, low light, and macro conditions captured with both cameras:
While neither is a raw powerhouse, JPEG processing suits casual editing and sharing well.
Performance ratings based on technical metrics and practical testing rank Panasonic higher for general speed and flexibility, whereas Olympus impresses with zoom range and sensor image quality.
